摘要
粉煤灰作为一种水泥替代物,已广泛应用于建筑工程中,并且大量的试验结果表明[1]:适当的粉煤灰掺量可以提高混凝土的耐久性。但在水工建筑物中,粉煤灰的掺入会导致其抗冲耐磨性能降低。通过分析比较,选用一种外加剂-HF外加剂,来激发粉煤灰的活性,从而使其共同提高混凝土建筑物的抗冲耐磨性能。试验结果表明:掺入HF外加剂的粉煤灰混凝土抗冲耐磨性能较未掺HF外加剂的粉煤灰混凝土的抗冲耐磨性能明显提高。
As a substitute for cement,the fly ash has been widely used in construction engineering,and the proper fly ash amount could improve durability of concrete.But the fly ash reduce the erosion and ebrasion resistance properties of hydraulic structure,so choose the HF additive to activating of reactivity of fly ash,then made them work together to improving the erosion and ebrasion resistance properties of concrete.The results of the experiment showed that：the erosion and ebrasion resistance properties of HF fly ash concrete is rose noticeably than the ordinary concrete.
